recovering. The installation of dirty oil tank is embedded under the ground. The ground raw oil adopts the hot water coil for oil heating after discharging
into the dirty oil tank. The heating time is about 23 hours. The unit applies the submerged pump and transmits the oil into the oil discharging buffer tank
after the melted ground raw oil flows through the filter screen for sand removal. The design selects oneφ3m × 15.6 m horizontal type oil tanks with
submerged pump. The caliber of heating coil is aboutφ60 and 200m in length.
Pumps
When caliber of loading crane pipe is about DN80, the loading time ≤ 30min and velocity of crane pipe ≤ 4.5m/s, the maximum loading flow is about 580m3/h

transmits into the three-phase separator water chamber in order to supple water content. Considering the small amount of sewage in initial stage, the
maximum liquid amount is about 10m3/h. As the maximum output flow rate is about 30m3/h in later stage, the design adopts water supply pump (Q =15m3/h, H
=60m, P =11kW) 3 of 11kW; two units for operating and one for standby.
For avoiding the situation that the dehydrating system fluctuates greatly when opening the auxiliary pump, the design adopts two auxiliary pump (Q =20m3/h,
H =60m, P =11kW) 2, so as to ensure the oil supply of oil discharging point is available for pumping into the dehydrating system in 24 hours;
One oil recovering pump of sewage settlement tank (Q =20m3/h, H =60m, P =11kW) is available as the standby unit for auxiliary pump respectively;
According to developing prediction, the sewage amount outside this station is about 10- 45m3/h. In initial stage it is unable to realize the continuous
transmission. One sewage pump (Q =60m3/h, H =60m, P =30kW) shall be arranged; one for transmission and one for standby; adopt the automobile for
transmission.
The thermal load of heating stove is about 1.3MW. The maximum flow of heating water is about 65m3/h. The design selects two heating pumps (Q for use
=60m3/h, H =60m, P =30kW); one for transmission and one for standby;
According to systematic calculation outside the station that the water amount is 0.6m3/h for each oil well of 231 oil wells in 2009 years and 9 oil
collecting groups, each heating water yield is about 2m3/h. The maximum water content of this station is about 156m3/h; the water valves are 13 groups;
